We have made considerable progress in recent years in numerical modelling, a traditional
field of excellence in which we enjoy an international reputation. Remarkable advances
have been made in hydro-sedimentary modelling of maritime, estuarine and river
environments, allowing us to predict morphological changes reliably over increasingly
long periods. Methodologies for studying the stability of large civil engineering structures
(dams, power plants) as well as their thermal and seismic behaviour have also progressed
enormously, leading to significant economic savings in their design. Our engineers
have an excellent knowledge of CFD (Computational Fluid Dynamics), enabling them to
perform detailed analyses of turbulent and complex flows and fluid-structure-sediment
interactions around facilities built in water.
We have also worked to perfect GIS (geographical information systems) that are used, for
example, to compare climate hazards with socioeconomic risks. Our teams now comprise
more than a hundred people specialising in these tools for modelling natural phenomena
and analysing and processing data, in addition to many other colleagues within the
Group working on systems for simulating thermal conditions in buildings, air flows, civil
engineering structures and electrical networks. This “fire power” is mobilised on a daily
basis in defining reliable, efficient and environmentally friendly solutions for the projects
we implement.
